Agitator Mechanical Seals

    Agitator Mechanical Seals
    Agitator mechanical seals are designed to provide a high degree of sealing integrity in demanding industrial mixing applications. These seals are composed of several components, including a rotating seal face, a stationary seal face, a spring or springs to maintain contact pressure, and a gland to hold the seal in place.Materials such as silicon carbide, tungsten carbide, or ceramic are typically used to manufacture the seal faces. These materials are highly resistant to wear and corrosion, and the rotating seal face is mounted on the agitator shaft and rotates with it. Meanwhile, the stationary seal face is held in place by the gland and remains stationary. The spring or springs are responsible for ensuring that the seal faces maintain constant contact pressure, which is essential for effective sealing.

    Agitator mechanical seals can be designed as single or double mechanical seals, depending on the specific application requirements. Single mechanical seals consist of a single set of seal faces, while double mechanical seals have two sets of seal faces separated by a fluid-filled chamber. Double mechanical seals are usually used in higher-pressure applications or when leakage cannot be tolerated.In addition to their sealing capabilities, agitator mechanical seals are designed to allow for a certain degree of axial and radial movement of the agitator shaft. This is important to accommodate the various movements that occur during the mixing process and helps to ensure that the seals maintain their effectiveness over time.Agitator mechanical seals are used to provide a seal for the shaft that connects the agitator blades to the drive motor. The seal prevents the process fluid from leaking out of the tank and also prevents contaminants from entering the tank. Agitator mechanical seals are commonly used in mixing applications in various industries, such as chemical processing, pharmaceuticals, food and beverage, and wastewater treatment.

    How it works:

    Agitator mechanical seals consist of two main parts: a rotating seal face and a stationary seal face. The rotating seal face is attached to the agitator shaft, while the stationary seal face is attached to the seal housing. The seal faces are held together by a set of springs that provide the necessary force to maintain a tight seal.

    When the agitator is in operation, the seal faces rotate with the agitator shaft. The fluid pressure on the seal faces creates a hydrodynamic film that provides a lubricating effect, reducing wear and increasing the lifespan of the seal.


    Agitator mechanical seals are used in applications where there is a need to mix fluids in tanks or vessels. They are commonly used in chemical processing plants, pharmaceutical production facilities, food and beverage processing plants, and wastewater treatment plants.

    Some common applications of agitator mechanical seals include:

    1. Mixing chemicals and ingredients in food and beverage production
    2. Blending pharmaceutical ingredients
    3. Mixing and homogenizing liquids in the chemical processing industry
    4. Wastewater treatment processes, including mixing and aerating wastewater
